The New York socialite, who has three-month-old son Eric with the music mogul, says the couple aren't in a rush to tie the knot and are simply enjoying parenthood.

Lauren - who was recently granted a divorce from millionaire ex-husband Andrew Silverman, the father of her eight-year-old son Adam - said: "Of course we will get married eventually, but not yet."

Meanwhile, Lauren thinks the couple's son Eric looks more like his famous father than her, and she isn't surprised by how well Simon has taken to being a father.

She said: "I think he's absolutely adorable! He does look a lot like his dad. He looks nothing like me.

"I'm not surprised, I knew he would be an amazing father. He's an amazing guy with a good heart. Sometimes when you get in a situation, you rise to the occasion and he really has. Simon's an amazing dad. It's so cute when I see them together. I just love it."

And it seems Simon's doting mother Julie is happy for the couple and their newborn, too.
